Patented Jan. 23, 1934 FURNACE RADIATOR Thomas Crick, Independence, Mo.,assigner to Independence Stove and Furnace Company, Independence, Mo., acorporation 'of Missouri Application October 6, 1930. SerialV No.486,709 3 Claims. (Cl. 126-102) `My invention relates to radiators andmore particularly to devices of that character for use in hot airfurnaces, the principal objects of the invention being to provide aradiator of novel construction for adapting coal furnaces for the use ofgas or oil, and increasing the heating emciency of the furnace.

In accomplishing these and other objects of my invention. I haveprovided improved-details of structure, the preferred form of which isillustrated in the accompanying drawing, wherein:

Fig. 1 is a perspective view of a furnace equipped with my improvedradiator, parts being broken away for better illustration.

Fig. 2 is a sectional plan View of the radiator.

Fig. 3 is a fragmentary section of the top of the radiator illustratingthe joint for the side and top wall members.

Referring in detail to the drawing:

1 designates a furnace of the conventional coalburning type herein shownconverted for the use of gas, the iire box 2 being fitted with gasburners 3 and with my improved radiator 4 replacing the radiatornormally used thereon for coal-burning purposes.

The radiator 4 is of the horseshoe type and in'- cludes a substantiallysemi-circular or arcuate casing having side walls 5 and 6 spaced-apartby end walls 7 and by top and bottom wall members 30 8 and 9 forming achamber 10 for receiving heat from the iire box 2, the end walls 7 beingspaced apart to provide an opening 11 whereby the radiator is adaptedfor fitting over inward projections on the front panel of theconventional type furnace.

Provided at the top and bottom ends of the side walls 5 and 6 areinturned and outturned flange portions 12 and 13 respectively, formingseats 14 engaged by peripheral anges 15 on the top and 40 bottom walls,the outturned portion 13 being lapped over the top and bottom walls at16 for se- Y curing the members and forming an air-tight joint with theside walls.

Located in the inclosure 17 formed by the inner wall 6 is a manifold 18including a hood p0rtion 19 for receiving heat from the iire box andhaving an open lower end 20 fitted with an adapter ring 21, whereby themanifold may be mounted over i'ire box openings of various sizes by theuse of adapter rings having portions 22 to lit the top edge 23 of the rebox.

Extending radially from the hood 19 of the manifold 18 in the form of anX'are conduits 24 and 25 for conducting heat from the hood 19 to thechamber 10. The conduits are clamped in fittings 26 on the inner wall 5,the conduits 24 Vcommunicating with the upper portion of the chamber 10adjacent the end walls 7 and the conduits 25 communicating with thechamber in a horizontal plane with the conduits 24 and sub- 60stantially mid-way between the conduits 24 and an outlet conduit 26. Theconduit 26 communicates withA the lower portion of the chamber v10 and'extends outwardly from the outer wall 5 diametrically opposite theopening 11 betweenthe 65 end walls 7 and is adapted for conducting theproducts of combustion from the chamber 10 after their passage throughthe retarding elements presently described.

Located in the chamber 10 on opposite sides of i0 of the radiator andwhich tend to retard iiow of heat from the chamber 10 to the outletconduit 26'.

in order to further retard the ow of heat through the chamber 10, Iprovide baffle plates 29 which are secured in the chamber to the top B6'and side walls and between the conduits 24 and 25 and are spaced fromthe bottom wall 9 to form an opening 30 so that heat from the conduits24 is directed downwardly in flowing toward the outlet conduit 26.

Located between the conduits 25 and outlet conduit 26 are bafe plates 31secured to the top and side walls and spaced from the bottom wall 9 fordirecting the flow of heat downwardly, and located between the baffles31 and outlet conduit 95 26 are plates 32 which are secured to thebottom and side walls and spaced-from the top wall for directing theiiow of heat upwardly and cooperating with the plates 29 and 31 and withthe tubes 27 in forming a restricted and tortuous passage A100 forretarding now of heat through the heating chamber 10.

in using my improved radiator, the heat produced by combustion of gas oroil in the furnace flows into the manifold 19 and is thereby evenly 105distributed to the heating chamber 10. The heated gases entering thechamber 10 are retarded in their iow to the outlet conduit 26incidentally permitting thorough heating of the side walls and tubes 27and causing upward move- 1'1"() ment of cold air through the furnace forcontact with the heated side walls and tubes whereby the air is heatedfor distribution to the building to be heated.

From the foregoing it will be apparent that a furnace radiatorconstructed in accordance with my invention will permit coal-burningfurnaces to be converted for the use of gas or oil at a minimum cost,and that the greater radiation and retarded flow of heat will eifect aconsiderable saving of fuel.

What I claim and desire to secure by Letter Patent is:

1. A radiator of the character described including an arcuate casinghaving inner and outer side walls and top and bottom walls forming achamber, an outlet conduit opening through said outer side wall, aninlet manifold concentric with said casing and having branches openingthrough said inner side wall for conducting heated2 gases to saidchamber, tubes extending through the chamlber and top andbottom walls,and baille plates fin the chamber interposed between said tubes andarranged to cause downward flow of gases into "said chamber upon issuingfrom each of said walls to form a chamber, an inlet manifold havingbranches communicating with said inlet openings for delivering productsof combustion into said chamber, tubes extending through the chamber andtop and bottom walls, and baille plates in the chamber interposedbetween said tubes and arranged to cause downward flow of said productsof combustion upon issuing from each of said branches and a succeedingupward and downward flow of said products before passing through theoutlet opening.

kfrom the outer wall and having inlet openings adjacent its ends and atpoints substantially midway between its ends and the outlet opening,topandbottom wallsconnecting said inner and 4`outer walls to form anarcuate chamber communicating with said outlet opening, an inletInaioifold having branches communicating with lsaid Ainlet openings fordelivering products of combustion into said chamber, tubes extending letopening.
